NullReferenceException is thrown when importing a PDF document containing InlineImage with missing parameters

When the document contains Simple Font with predefined encoding and no ToUnicode mapping the text should be extracted with the following algorithm:

• Map the character code to a character name according to the font’s Differences array.
• Look up the character name in the Adobe Glyph List to obtain the corresponding Unicode value. 
  

Currently, the PdfProcessing library doesn't map the character code properly which leads to wrongly encoded text content.

CryptographicException is thrown when saving with PdfStreamWriter or importing with PdfFormatProvider.

The exception: System.Security.Cryptography.CryptographicException: 'The input data is not a complete block.'

The Form object does not inherit the graphics state of the page

Currently Type0Font class has CMap that can only be Identity-H. The Identity-V is a vertical version of Identity−H. The mapping is the same as for Identity−H.

The exception is thrown when CIDSet is imported.

I am using the trial version of telerik for xamarin for .net core which was released last year, to convert pdf to text. Our service is hosted in Azure. The text which I get back, in certain cases the spaces are missing (say for example instead of 'I [am] here', it displays 'I[am]here'. This happens randomly. 

The code which we have used is as follows -

byte[] pdfBinary = Convert.FromBase64String(inputString);

 TextFormatProviderSettings textFormatProviderSettings = new TextFormatProviderSettings("\r\n", " ");
         
 var textFormatProvider = new TextFormatProvider();
 var pdfFormatProvider = new PdfFormatProvider();

 RadFixedDocument document = pdfFormatProvider.Import(pdfBinary);
 result = textFormatProvider.Export(document, textFormatProviderSettings);

At this point, the import logic cannot automatically repair such documents and a NullReferenceException is thrown while reading them. You could repair the invalid file using the project from the attachment.

Implement Replace method(s) which enable the users to replace a concrete string/content/text in a PDF document (RadFixedDocument).

Workaround: 
Check the sample project attached ("RemoveText.zip") that demonstrates how to remove text separated into several text fragments.

A KeyNotFoundException is thrown when trying to open a PDF containing specific Type1 font.

Hello Telerik,

Last time we attempted this the <Viewbox> contents would not render and were empty upon xaml to pdf output. It would be great if you had this feature and we could move completely away from raster output to PDF for controls that contain Viewboxes. Otherwise we have really liked the PDF's created by the tool, the vector output is sharp as expected.

Thank you,

Patrick

Add support for movie annotations.

The values of rotated widgets on a rotated page are invisible after exporting them. The value can be seen only while editing a field.

Add support for R16 color space

Currently adding an Image content element with ImageQuality different from High leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Currently adding an Image content element with ImageSource instantiated with a GIF file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Add support for documents with an invalid stream cross-reference table

PDF/UA (PDF/Universal Accessibility) is the informal name for ISO 14289, the International Standard for accessible PDF technology.

Exception when the endstream is no on a new row 

When merging or splitting files that contain the "159 '\u009f'" char, ArgumentException("The encoding is not supported.") is thrown.

This issue can also result in ArgumentException in client applications with the message: currentIndirectObject should be null.

Workaround:

Use PdfFormatProvider or reflection to register the char (check the comments).
